Physical properties
Hardness of 6-6.5 on the Mohs scale, brass-yellow color, metallic luster, isometric crystal system with distinct cubic habit, and greenish-black streak.
Formation & geological history
Forms in hydrothermal veins, sedimentary rocks, and metamorphic deposits through the precipitation of iron and sulfur under reducing conditions.
Uses & applications
Used historically for ignition in firearms, currently utilized in the manufacture of sulfur dioxide and sulfuric acid, and popular as a mineral specimen in collections.
Geological facts
Commonly known as 'Fool's Gold' due to its superficial resemblance to real gold, though it is much harder and more brittle.
Field identification & locations
Easily identified by its brassy metallic luster, high hardness that scratches glass, and cubic crystal formations. Found worldwide, notably in Peru, Spain, and the USA.
